Title:
  xenapi: metadata updates causing rebuild and resize to fail

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  When you update instance metadata during tasks where the VM is not
  available, such as resize or rebuild, its possible you get NotFound
  exceptions causing the instances to go into the Error state, which
  resets the Task state, which then causes instance updates to fail that
  are part of the long running operation.

  This should not happen, as change_instance_metadata can only be called
  when the task_state=None, however there is clearly a window where the
  metadata request has been made, and the resize or rebuild has started
  in the mean time, and so the NotFound error is raised.

  To avoid this, we can silently fail metadata updates where the VM
  cannot be found, as the latest metadata will be added back into the VM
  when it is being configured on the destination.
